tricky, ptp's are hard to appraise because of their relative rarity these days. I'd pay a good 150 for the bodies, but that's me, dunno if anyone would pay more or less.
An omen in nice condition you could easily get 80-100 for it. Near little blowbacks.
you have the pneus for those markers? i always did like PTP's mags and 'cockers. i have no idea what anything's worth in today's market, though. collectibles are the only thing retaining any value, but then, like anything else, they're only worth what someone will pay for them.
